The Browns have used 25 quarterbacks since 1993, including Todd Philcox and Ken Dorsey.

Even the Colts, with a long stretch of Peyton Manning and now Andrew Luck, have used 13 quarterbacks over the last 20 years.

In theory, the Packers could still sign Flynn, who is currently a free agent, to keep the total at three.

The Packers certainly deserve credit for developing Favre and Rodgers into franchise quarterbacks, but to go 20 years without any significant injuries to those quarterbacks -- and without any significant drop off in production that would lead to a change -- is incredible.
